The Letters Patent No. 1,638,671, of Aug. 9, 1927, describes a roofingfastening for undulated roofing plates of asbestos-cement, known in thetrade under the name of Eternit, glass, metal or the like. These fastenings comprise a fastening rod which projects upwardly through aperforation inat-least one of the over1apping"pl'ates and which has itslower end rigidly engaged-with the adjacent member oftheframeworlnarigid strengthening member through-which said rod extendshaving its entire upper face fitting flush against the inner surface ofthe perforated plate; a malleable metal washer mounted onthe'projectin'g portion of the rod and disposed'against" the externalsurface of said perforated plate; and a clamping member threaded on'saidprojecting rod portion and anchored in'the external surface of saidwasher. These special fastenings enable a fixing of the roofing platesindependently of their support, thus being protected against damagesresulting from deformations of the support or of the roof construction.Furthermore, the fast'enings are even then'watertightwhen the fixingscrew becomes unscrewed;

The object of the present invention concerns essential improvements ofthese roofing fastenings. i

The drawings show some embodimentsof the invention, by way of example,

Fig. 1 shows the fastenings for roofing plates destined to be fixed onwooden purlins or supports; 1

Fig. 2 shows a-modified form destined to be fixed at doubleT-g'irders;Fig. 3 shows the fastening's asfthey are used to be fixed at the lowest'purlin or Fig. 4 is a perspecti'veview of a detail, i. e. a supportused for the fastenings sho'w'n inFig.3; p '5 Fig. 5 shows also adetail, if'e. afltigh'tem ing disc in perspective view together with theimplement for its fitting up "oradjusting;

Fig. 6 is a vertical crosssection'through said tightening disc. w a IThe fastenings of undulatedroofing plates platesi A j'yasher Z/withscrew-threaded bush Eco-operating with theJscreW-threadedend 9 (Fig. 1)of1theeye bolt g i-'g rests against the bush-shaped-part m of thebearing disc anther-latter being roun d, ovalor polyg- --onal' shapedand adapted-to the form of the et-aid b',"destined to'be fixed at awooden p'urlin c, consist of a metallic bolt 05, each extremity"having'an eye (5 and to which now;isfobtained,fromwhich results abetteradjustment of the bolt 9-9 for the. "case in which the purlins orgirders are not'exactly uniformly spaced. Further- 'more, therefromresults the advantage that the roofing plates can be perforated byappropriatemachines in' the manufactory or "workshop'accord ng'to-agauge, avoiding a preliminary adjustment relative to the laid purlins;'From' this results an easy, quick andifcheap erection' and assemblage ofthe roof; The'linked-bolts are previously fixed to thereof constructionsubdivided by an appropriate lining out, for instance to'wooden'purlins.

Fig.2 shows he... the two bolts Fi e} and 9-93 hinged together are fixedto a double T-girder 7b. VVhilst the lower part of the bolt 'z'"embraces the lower flange of the girderin the form of a hook, the upperpartkept by -a strip of sheet metal is having afcorresponding aperturefor said bolt Afteri fixing of its eye in the manner shown in'Fig. '2,the strip of sheet metal is is bent round the upper flange of the girderh; thus enabling the'fixing of'the linked bolt preliminary to the quickcontinuous -mounting; Here the eye of the lower bolt z 1 has a astretched oval shape for compensating an irregular distance between thepurlins for wexactl'y- -machine-perforated roofing roofing plate, whilstthe bush has at its upper end an upward flange forming an annularconcave seat, so that the coneshaped washer Z, cooperating with thisseat, secures also during deformations of the girder or of the purlin awater-tight joint. An overlapping depending collar l of the washerguides rain water :on the bearing disc m projecting on all sides oversaid washer, and from this disc m on the roofing plate I).

As the screw-threaded bush is higher than the upper outer edge of thecone-shaped part, the water accumulating .on the latter will never reacheither the upper edge of the bush of the washer or the screw-threaddistance and to protect the roofing plate 1b against the pressureexerted by the screw bolt. The upper part of the "tube m 10f thetightening disc n being cone-shaped, an occasional capillary actionEbet-ween the bush m and the tube 42 is avoided.

The tightening disc n will ;be moved %laterally during assembling theroofing plates by means of an adjusting implement p, for compensatingthe irregularities of the distances between thexpurlins. The tube of thetightening disc n serves :as ian:,ad'just- .ing stop for the :nextroofing :plate The strip 10f sheet anetal 10 soldered to the disc .11 iscatched at its bent up grip L01 by means of said small implement p, asshown in Fig. 5, and then ibent mound the .border of the roofing ,plate.aa, :as :shown Figs. 1 and :6, after adjustment of the :seat

-of the tightening disc In. In this manner,

the two roofing :plates are Jfixed to one :an-

--other.

For giving the necessary fSlii'fiIlQSS to the roofing fixed by means ofihingedly :connected members clasped rto themoofconstruction, and .forpreventing the roof rfirom giving -way by slipping in the direction ofthe inclination of the roof, special supports .:q are mounted on thelowest purlin 0 mm theupperedgeof the external wall (Figs. 3 and 14).

This-support g :has two :parallel lateral arms withrapertures :9 and ql1keep mg and maintaining the eye zbo'lt zy g "in right and determinedfixed position :with relation to the direction of roof ,sinclination,but leaving a lateral play or clearance.
